Dynamic DNS sites you might want to block

These domains belong to ChangeIP.com, which I guess is a legitimate company providing Dynamic DNS services, but one that is being abused by the bad guys. These will be used with some random subdomain unless it's a corporate site (like ChangeIP.com itself) pointing to a random IP address somewhere.. so blocking IPs won't work here.

There are two versions of this list, one links through to the Google Safe Browsing diagnostics report in case you want to review them on a case-by-case basis before blocking them (yellow highlighted ones have some malware, red highlighted ones are blocked by Google). The second one is a plain list of everything in case you want to block them completely.

You might notice one of the domains is called b0tnet.com which is a peculiar name for a legitimate business to register.
